Tim Kaine is wailing on a harmonica at a brewery in Asheville, North Carolina, after a campaign stop in this swing-state city.

The Democratic vice presidential nominee stood in with a local bluegrass band at Catawba Brewery and sang harmony on a couple tunes, including Bob Dylan's "Wagon Wheel."

Kaine and his wife, Anne Holton, stopped by the brewery after eating dinner next door at Buxton Hall Barbecue.

Earlier, Kaine headlined a rally at a community center, sharply critiquing Republican nominee Donald Trump's decision not to release his personal tax returns. He told several hundred supporters, "Americans have a right to know what the financial situation is."

Kaine made no mention of the speech Trump made Monday on terrorism and immigration.

Joe Biden and Hillary Clinton are making an impromptu stop at the vice president's boyhood home in Scranton, Pennsylvania.

Biden and Clinton's motorcade stopped at the modest gray two-story home after a fundraiser nearby.

In a brief exchange with reporters, Clinton says that while some voters in Pennsylvania may back Donald Trump, "nobody will love Scranton more than I will as president."

Donald Trump is proposing an immigration policy which would feature "extreme vetting" and an ideological test for admission to the United States

Trump, in a foreign speech Monday in Ohio, claims that many recent terror attacks in the U.S. have been carried out by immigrants or the children of immigrants.

He said he would temporarily suspend immigration from nations with a history of "exporting terrorism" and would ask the State Department for a list of regions where screening is not currently adequate.

Trump said:"The time is overdue to establish a new screening test for the threats we face today." The Republican nominee also said the U.S. should screen out "any who have hostile attitudes to our country and its principles."

Trump's mother and wife were immigrants.

Donald Trump says a key component of his foreign policy would be "halting" the spread of "radical Islamic terrorism" by limiting their access to the Internet.

The Republican presidential nominee isn't saying how he would accomplish that goal in a foreign policy speech in Youngstown, Ohio.

But he says "We cannot allow the Internet to be used as a recruiting tool."

He adds that "any country that shares this goal will be our allies."

2:50 p.m.

Donald Trump says that his Democratic rival, Hillary Clinton, lacks "the mental and physical stamina" to take on the Islamic State group and the "many adversaries we face."

Trump is delivering an anti-terror speech in Ohio as he tries to steady his floundering campaign.

He is blaming the former secretary of state and President Barack Obama for enacting policies that allowed the IS group to spread.

Trump says that maybe it would have been better if, instead of traveling the globe, Clinton had stayed home.

Clinton is the first woman to win the nomination of a major political party.

___

2:46 p.m.

Donald Trump is delivering a foreign policy address and, once again, blaming President Barack Obama for the rise of the Islamic State group.

Trump, speaking Monday in Youngstown, Ohio, suggested Obama did not display "moral courage" during what the celebrity businessman dubbed the president's international "apology tour," which included a 2009 stop in Cairo.

Trump did not call Obama "the founder of ISIS," a remark which drew criticism last week. But the Republican nominee said Monday that Obama's policies "led directly to the rise of ISIS, without question."

The Republican nominee's foreign policy address comes during a rocky stretch for his campaign. He's struggled to stay on message and has consistently overshadowed his policy rollouts, including an economic speech last week.

The Senate's Democratic leader says Donald Trump should take the naturalization test that all immigrants go through to become citizens as the Republican presidential nominee pushes new tests on those trying to enter the United States.

Trump has called for a ban on foreign Muslims entering the United States. He was expected to propose a new immigration policy on Monday in which the U.S. would stop issuing visas in any case where it cannot perform adequate screenings.

Vice President Joe Biden says Donald Trump "would have loved Stalin."

Biden made the remark in his hometown of Scranton, Pennsylvania, at a rally for Democrat Hillary Clinton. He noted that the Republican presidential nominee has voiced praise for Russian President Vladimir Putin and the late Iraqi dictator Saddam Hussein.

If Trump likes them, "He would have loved" Joseph Stalin, leader of the Soviet Union until his death in 1953.

Scholars estimate that under Stalin, more than 1 million people were executed in political purges and millions more died as a result of harsh labor and cruel treatment in the vast gulag prison camp system, mass starvation in Ukraine and southern Russia, and deportations of ethnic minorities.

2:10 p.m.

Joe Biden is attacking Donald Trump, saying the Republican nominee "has no clue" about foreign policy, the lives of working class Americans and has "un-American" policy ideas.

Biden says: "He's trying to tell us he cares about the middle class? Give me a break. It's such a bunch of malarkey."

The vice president says Trump is "unqualified" to be president, arguing he lacks any kind of foreign policy experience or interest to learn about international challenges. If Trump had been president, Biden says he would have urged his late son, Beau, not to serve in the military because Trump would not be a trustworthy leader.

Biden says he's heading this week to Kosovo to reassure NATO countries that America stands by its alliances — a commitment he says Trump has weakened.

Joe Biden is offering a powerful testimonial for Hillary Clinton, saying having the first female president will have a major impact on women and girls across America.

He says, "It will change their lives."

The vice president says he's known Clinton for three decades, dating back to before her time as first lady in the 1990s. He says voters know that Clinton is "smart," ''tough" and "bright," but don't recognize her passion for helping improve the lives of America's working and middle class.

"There's only one person in this election who will possibly help you and that is Hillary Clinton," he says. "She's always been there."

Biden and Clinton are holding their first campaign event together in Scranton, Pennsylvania Both have personal ties to the Rust Belt city.

At a rally in Scranton, Pennsylvania, Monday, Clinton noted that Trump had said he offered care at his businesses. But she added, "like so much of what he says, it's not true."

The Associated Press reported last week that Trump had made the claim last year in Iowa, but that there was no evidence to back it up. Rather, Trump appeared to be referring to child care programs offered to guests at his hotels and golf club, when he talked about "Trump Kids" and "Trumpeteers."

Clinton noted the services for children at Trump hotels, adding: "if you work for his business, if you clean the room, water the lawn, carry people's bags, you get nothing."

Hillary Clinton says that if elected, she plans to ask Joe Biden to continue his effort to end cancer by improving research and treatment of the disease.

The Democratic presidential nominee is holding her first campaign event with the vice president on Monday in Scranton, Pennsylvania.

She's touting their shared background in the working class, Rust Belt city. Biden was born in Scranton and Clinton spent summers there visiting her grandparents.

She says: "Oh Joe, I hope you know how much not just Scranton but America loves you and your family."

Biden launched his cancer moonshot initiative after his son, Beau, died of brain cancer in 2015. The White House has requested $1 billion dollars in funding for the program, a request Clinton has urged Congress to approve.

11:35 a.m.

Republican Rep. Mark Sanford, who served as governor of South Carolina, suggests he could abandon his support for Donald Trump if the GOP presidential nominee fails to release his tax returns.

In an op-ed in Monday's New York Times, Sanford describes himself as a conservative who has little patience for Trump's personal style and "penchant for regularly demeaning others." However, Sanford is backing the nominee because of the Supreme Court vacancy and the possibility that the next president could fill several openings.

Whether Sanford remains in the Trump camp is contingent on the nominee's release of his tax records.

Sanford writes that there is a precedence for such transparency. The congressman also pointed out that Trump had criticized 2012 nominee Mitt Romney for moving slowly in releasing his tax returns.

4:35 a.m.

Democratic presidential nominee Hillary Clinton is getting an assist from Joe Biden in Pennsylvania on Monday. The vice president plans to call Donald Trump the most uninformed presidential nominee in history.

Biden is holding his first campaign rally with Clinton in his hometown of Scranton.

Biden's office says he will argue that Trump, the Republican hopeful, is less prepared on national security than any nominee in history. And he'll say that Trump's erratic rhetoric and "bluster" will make Americans less safe.

Biden is also expected to make a pitch for Clinton's plans on the economy and education. It comes as Clinton has pressured Trump to release his tax returns and questioned his jobs agenda for middle-class workers.

Republican Donald Trump says he will replace nation building with what aides are calling "foreign policy realism" focused on destroying the Islamic State group and other terrorist organizations.

This will come in a speech in Ohio Monday laying out his vision.

The GOP presidential candidate will argue the country needs to work with anyone that shares that mission, regardless of other disagreements.

Trump is also expected to propose a new immigration policy under which the U.S. would stop issuing visas in cases where adequate screenings can't be performed.

And he's expected to propose creating a new, ideological test for admission to the country that would assess a candidate's stances on issues like religious freedom.
